MENTS, TO THE OHIO NEW JERSEY KIRK, OF ST. ALBANS, WEST VIRGINI ATTACHABLE WELDING TERMINAL Application filed December 30, 1926, Serial No.

The invention relates to rail bonds for bonding railroad rails used as conductors ofelectricity and the like; and more particularly to an attachable terminal for such bonds.

In the rail bonds which are at present in common use the bonds are usually furnished with the terminals attached thereto.

The object of the present invention is to provide an attachable terminal punched or pressed from sheet steel so that the consumer or user can make his own bonds from scrap copper such as motor cables, field coils, armature coils and the like, the improved attachable terminals being easily and readily trated in the accompanying drawing, in

5 which Figure 1 is a perspective view of a portion of a rail showing one end portion of a bond attached thereto by means of the improved terminal;

Fig. 2, a bottom plan view of the improved terminal showing one end portion of a bond conductor clamped therein;

Fig. 3, a section on the line 3-3, Fig. 2, and

Fig. 4:, a perspective view of the under side of the improved terminal showing the same in the original condition, before attachment of the conductor.

Similar numerals refer to similar parts throughout the drawing.

The conductor 1 may be formed of a series of copper wires, strips or the like, one of the improved welding terminals 2 being arranged to be attached to each end of the conductor. This terminal is formed, as by stamping or punching, from sheet steel of sulficiently heavy gauge and includes the curved end 3, to receive the end portion of the copper conductor, and the flat end f adapted to fit snugly upon the upper surface of the 158,019.

base flange 5 of the railroad rail indicated generally at 6.

The curved end portion 3 of the terminal is shaped to receive the adjacent end portion of the conductor 1, and is provided with a pair of integral ears 7 punched or stamped from the terminal and adapted to be bent over the conductor to hold the'saine, as shown in Figs. 2 and 3.

A substantially triangular ear 8 is formed :50

at the outer edge of the flat end portion of the terminal and bent at a suitable angle to fit snugly against the under side of the base flange 5 of the rail when the terminal is po side of said flange.

sitioned upon the upper he end of this ear is preferably sharpened as at 9 to permit the same to be driven between the bottom of the rail and a tie.

The center of the a welding pool to receive the molten metal, indicated at 11, when the bond is welded to the rail.

In order to provide for fusing the rail, terminal and conductor together, with this weld- '5},

ing, the end of the conductor is extended a short distance across the opening 10 of the terminal, thus extending the copper conductor into the welding pool and causing the conductor, as well as the terminal, to be welded to the rail.

Nhen the bond is welded upon the rail, as shown in Fig. 1, the curved portion 3 of the terminal is so positioned flange of a wheel contact with the same, shape of the terminal will tend to cause the wheel flange to ride down upon the curved surface without damaging either the bond or the weld.

From the above it will be seen that a simple and inexpensive attachable welding terminal is provided which may be easily and readily attached to any copper conductors which the user may provide, and which may A be easily and quickly positioned upon the rail or,

and welded thereto, the puddling pool holding the molten metal at the desired place and fusing the terminal and copper conductor to the rail and to each other.
